AS3 - 编译器错误1120：未定义的属性* 7

Question

的错误&源的访问：

1120: Access of undefined property projectsNum. 
projectsNum = projectTitle.length(); 

1120: Access of undefined property newsTitleArray. 
newsTitleArray = xmlData.news.article.title.text().toXMLString().split("\n") ; 

1120: Access of undefined property newsTitleArray. 
newsTitleArray.reverse(); 

1120: Access of undefined property newsInfoArray. 
newsInfoArray = xmlData.news.article.info.text().toXMLString().split("\n") ; 

1120: Access of undefined property newsInfoArray. 
newsInfoArray.reverse(); 

1120: Access of undefined property newsContentArray. 
newsContentArray = xmlData.news.article.Content.text().toXMLString().split("\n") ; 

1120: Access of undefined property newsContentArray. 
newsContentArray.reverse(); 

我的XML行动的行动，我怀疑的错误是：

//XML LISTS// 
//=========// 

var projectTitle:XMLList; 
var projectAuthor:XMLList; 
var projectImage:XMLList; 
var projectProgz:XMLList; 
var projectHyper:XMLList; 

var newsTitle:XMLList; 
var newsInfo:XMLList; 
var newsContent:XMLList; 

var projectNum:Number; 
var newsNum:Number; 

var xml:XMLLoader = new XMLLoader(this,"data.xml"); 

function getXML(xmlData:XML):void { 

    projectTitle = xmlData.projects.project.Title; 
    projectAuthor = xmlData.projects.project.Author; 
    projectImage = xmlData.projects.project.image_path; 
    projectProgz = xmlData.projects.project.Progz; 
    projectHyper = xmlData.projects.project.link; 

    newsTitle = xmlData.news.article.title; 
    newsInfo = xmlData.news.article.info; 
    newsContent = xmlData.news.article.content; 

    projectsNum = projectTitle.length(); 
    newsNum = newsTitle.length(); 

    newsTitleArray = xmlData.news.article.title.text().toXMLString().split("\n") ; 
    newsTitleArray.reverse(); 

    newsInfoArray = xmlData.news.article.info.text().toXMLString().split("\n") ; 
    newsInfoArray.reverse(); 

    newsContentArray = xmlData.news.article.content.text().toXMLString().split("\n") ; 
    newsContentArray.reverse(); 

} 

the source files files

，我不发布任何其他代码因为我不知道错误可能在哪里，但我已经上传the source files files如果你需要他们

Answer 1

当看到错误：

1120: Access of undefined property 'VariableName'.

这意味着还没有定义或（访问它时，作为对象/类的属性或功能）声明的变量。这里是一个概述：

1120: Access of undefined property projectsNum. 
projectsNum = projectTitle.length(); // You have declared [var projectNum:Number;] Error source = s --> project[s]Num [Reason #1] 

1120: Access of undefined property newsTitleArray. // I do not see a declaration for this variable [Reason #2] 
newsTitleArray = xmlData.news.article.title.text().toXMLString().split("\n") ; 

1120: Access of undefined property newsTitleArray. // [Reason #2] 

newsTitleArray.reverse(); 

1120: Access of undefined property newsInfoArray. // [Reason #2] 

newsInfoArray = xmlData.news.article.info.text().toXMLString().split("\n") ; 


1120: Access of undefined property newsInfoArray. // [Reason #2] 

newsInfoArray.reverse(); 


1120: Access of undefined property newsContentArray. // [Reason #2] 

newsContentArray = xmlData.news.article.Content.text().toXMLString().split("\n") ; 


1120: Access of undefined property newsContentArray. // [Reason #2] 

newsContentArray.reverse(); 

似乎是一个简单的错误给我。我希望这有帮助。
